I run the chrome unit like Challangers.Been in th 65 since 2000.No problems ever but I dont have much draw.My kid uped the alt in the 62 300 when he had it went from 35 to 65.ran it for almost 15 years.no problems and he ran a big stereo and hi output headlight but they were halogens like in my 65.Alt wont usually creat a problem unless you have lots of after market add ons.I do bypass the amp meter as they were bad even new.A larger alt and replacing the points reg with the solid state makes idle lighting better.Rocky
